Louis was hurt during Sunday's game against Minnesota when he was on the wrong
end of a blindside block from Vikings defensive lineman Jared Allen on an
interception return.

The Bears questioned the hit after the game, as Allen appeared to launch
himself into Louis while blocking for Antoine Winfield. Allen was asked about
it afterward and said he believed it was a legal hit.

Louis had started all 11 games at right guard for the Bears this season and
has 28 starts in 41 games played over four seasons with Chicago.
